Quick Detail

 

General Longitudinal Fin Tube Production Capacity

General Specifications of Longitudinal Fin Tube

Welding Facility: 1 finning machine;

Daily production capacity up to 500 Meters;

 Fin type: U fins,perforated,twist...

Tube OD: 19mm min.

Tube Length: 18 meters max.

Fin number: 2/ 4/ 8/ 16/ 18/ 32/ 36 piece per row 

Number of fins: 16/20/24/32/40

 

 

Description:

Manufacturing process: The longitudinal I/L or U shape fins are welded onto the core plain tubes by resistance welding or welding with filler matal (Spot welded).

  1. U bends tubes with longitudinal fins and fintube coils are avaiable for requesting.

  2. Longitudinal fins types: one-piece shape, standard U bent shape, cut & twist, perforated type etc…

  3. The fin channels are welded to the tubes in opposite pairs. Fin height, number of fins and fin thickness can be specified.

  4. Fins can be applied to either OD tube or NB pipe.

 

Applications:

The longitudinal finned tubes are wildely used in following fields.

1.    Chemical- ,petrochemical-,oil-, and power indudtry

2.    Heat exchanges

3.    Fired heaters

4.    Gas coolers and heaters

5.    Tank heaters.

 

Specifications:

Materials of tubes: Carbon Steel(A106/A179/A192/A210)

                                  Stainless Steel(TP304/TP304L ,TP316/TP316L) 

                                  Alloy Steel (T11/T22)

Fins Materials: Carbon Steel, 

              Stainless Steel(TP304/TP304L,TP316/TP316L, TP409/TP410)

Bare tube size: OD 19.05mm-OD60mm 

Fin number: 2/ 4/ 8/ 16/ 18/ 32/ 36 piece per row 

Number of fins: 16/20/24/32/40

 

Competitive Advantage:

1.    Longer working life than others ordinary welding helical fin tubes.

2.    Much safer and energy saving.

3.    Increase the heat transfer rates for viscous liquids.

4.    Perforated fin type used whenever drainage of liquid from fin channels become a problem.

5.    Longitudinal fin tubes are widely used in horizontal heat exchangers.
